Norma also buys a purple 1, Vee. I think she lives in another country, as I haven't seem them on the supermarket shelves in Au. Why can't the purple ones be grown 'here'? Wouldn't they look nice with the other coloured ons, in a curry or salad?!

I totally agree, miro_. Actually, I once bought purple sweet potato thinking it would look brilliant with the other coloured potatoes. Needless to say, I was disappointed when I peeled it, and it was white!
